REFCLK input is internally dc biased. AC coupling should be used.
Reference clock frequency is selected to ensure that the second harmonic is out of the bandwidth of interest.
PD inputs set at 400 MHz with divide-by-4 enabled.
The charge pump current is programmable in eight discrete steps; minimum value assumes current sharing.
For 0.75 V < V
These differential inputs are internally dc biased. AC coupling should be used.
The charge pump supply voltage can range from 4.75 V to 5.25 V.
DAC output is differential open collector.
For 1 dB output compression; input power measured at 50 Ω.
See Figure 35 and Figure 36 for timing diagrams.
See Figure 34 for timing diagram.
SYSCLK = REFCLK/x, where x is 1 or 2, as set using CFR[6].
